Description
Technical field
The utility model belongs to medium voltage electricity and becomes distribution technique field, in particular to a kind of level-one Sub-gate release device.
Background technique
Breaker plays the role of carrying in electrical power distribution system, cut-offs and making current, at present intermediate voltage electric power system
The breaker overwhelming majority being related to uses spring operating mechanism, and core component operating mechanism is the important composition portion of breaker
Point.As breaker and related component maturity step up, the medium-voltage equipment time between overhauls(TBO) is lengthened, the reliability requirement of equipment
It is higher and higher.
Present separating brake tripping is that two-stage is threaded off, and realizes separating brake tripping, but separating brake semiaxis and the sincere son of separating brake by separating brake semiaxis
Between snapping amount directly affect separating brake performance.Snapping amount is big, and separating brake is difficult, and causes low-voltage separating brake unreliable, snapping amount
The small combined floodgate that will lead to cannot keep.
Therefore, it from mechanism reliability consideration is improved, needs to design a kind of level-one Sub-gate release device, it is whole to improve breaker
Performance.
Summary of the invention
In view of the deficienciess of the prior art, the utility model provides level-one Sub-gate release device, change traditional tripping side
Formula is changed to de- simplify of level-one by two-stage tripping and threads off, simplifies tripping link, improves mechanism reliability.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is: level-one Sub-gate release device, including
Mounting plate, the separating brake buckle releaser being installed on mounting plate, bent plate, win in succession and be used for and the roller separating brake of breaker tripping point
The sincere son of lock, the bent plate are fixed on mounting plate by the first pivot pin, and bent plate can be rotated along the first pivot pin, the upper end won in succession
It is connect with bent plate, the lower end won in succession and the sincere sub- connection of separating brake, the sincere son of separating brake are fixed on mounting plate by shaft, and separating brake is sincere
Son can be rotated along shaft.
Further, it is connected between the upper end won in succession and bent plate by the second pivot pin, the lower end won in succession and separating brake are sincere
It is connected between son by third pivot pin.
Further, the bent plate is equipped with connecting lever and driving boss, and connecting lever offsets with separating brake buckle releaser activity, drives boss
It is flexibly connected with the upper end won in succession by the second pivot pin；When "on" position, the driving boss is in a high position, when gate-dividing state,
The driving boss is in low level.
Further, the sincere attached bag of the separating brake includes sincere sub- end and operating side, and the lower end of operating side and bent plate passes through third axis
Pin connection, sincere sub- end connect with roller.
Further, when "on" position, the sincere sub- end of the sincere son of separating brake and roller contact；When separating brake, the separating brake is de-
Button device electrification moves right, and bent plate is pushed to rotate clockwise along the first pivot pin, and described win in succession moves down, and the sincere son of separating brake is along shaft
It rotates clockwise, the tripping of sincere sub- end and roller.
Compared with prior art, the utility model advantage is:
The utility model redesigns tripping device for breaker knife switch, and traditional two-stage tripping is reduced to level-one tripping,
Separating brake semiaxis and the sincere sub- tripping of separating brake are not used, so as to avoid the snapping of separating brake semiaxis and the sincere son of separating brake to separating brake performance
It influences, the level-one trip gear of this programme simplifies tripping link, mechanism reliability is improved, so that it is more reliable to realize separating brake.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1. separating brake buckle releasers；2. bent plate；3. the second pivot pin；4. winning in succession；5. third pivot pin；6. operating side；7. sincere son
End；8. shaft；9. roller；10. the first pivot pin；11. mounting plate；21. connecting lever；22. driving boss.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is further described the utility model.
As shown in Figure 1, level-one Sub-gate release device, including mounting plate 11, the separating brake buckle releaser being installed on mounting plate 11
1, bent plate 2, win in succession 4 and be used for and 9 separating brake of roller of breaker tripping the sincere son of separating brake.Bent plate 2 is fixed by the first pivot pin 10
In on mounting plate 11, bent plate 2 can be rotated along the first pivot pin 10, and 4 upper end of winning in succession is connect with bent plate 2, win in succession 4 lower end and separating brake
Sincere sub- connection, the sincere son of separating brake are fixed on mounting plate 11 by shaft 8, and the sincere son of separating brake can be rotated along shaft 8.
Specific connection type is as follows: bent plate 2 is equipped with connecting lever 21 and driving boss 22,1 activity of connecting lever 21 and separating brake buckle releaser
Offset, driving boss 22 is flexibly connected with 4 upper end of winning in succession by the second pivot pin 3, win in succession 4 lower end and separating brake it is sincere it is sub between it is logical
Cross the connection of third pivot pin 5；And the sincere attached bag of separating brake includes sincere sub- end 7 and operating side 6, operating side 6 and the lower end of bent plate 4 pass through third axis
Pin 5 connects, and sincere sub- end 7 can connect or disconnect with roller.
The working principle of the utility model is as follows:
When "on" position, driving boss 22 is in a high position, and the sincere sub- end 7 of the sincere son of separating brake is contacted with roller 9；Gate-dividing state
When, driving boss 22 is in low level, and separating brake buckle releaser 1 is charged, fast moved to the right, pushes bent plate 2 suitable along the first pivot pin 10
Hour hands rotation, win in succession 4 moves down under the drive of bent plate 2, and the sincere son of separating brake is rotated clockwise along shaft 8, to realize sincere son
End 7 is threaded off with roller 9, realizes quick acting switching-off.
